Obstructive Sleep Apnea: Sleep Study Preparation

Pajamas or any comfortable sleep wear, preferably with a button-down front. A nightgown is impractical for attaching electrodes or straps to the chest and lower abdomen.

Your favorite pillow and blankets. The sleep laboratory will provide pillows and blankets, but yours may help you sleep better.

Toiletries such as toothbrush, toothpaste, hairbrush or comb

Clothes for the following day

Any needed medications

A book or other reading material

A snack, if desired

Things to do the day of your test:

Wash and dry your hair on the day of your sleep study. Do not use any hair products, such as gels, hairsprays or heavy conditioners, because these may prevent the electrodes from sticking to your scalp.

Ask your doctor or call the sleep laboratory to ask if you need to remove nail polish and/or artificial nails. The oximeter that is placed on your finger to monitor blood oxygen levels reads this information through the nail.

Generally, you will be asked to continue to take your regular medications. You will be notified in advance if you should alter your medications on the day of the test.

Do not drink any caffeinated beverages after noon on the day of your study.
